Namespace:  Alphaleonis.Win32.Filesystem
Assembly:  AlphaFS (in AlphaFS.dll) Version: 2.0
Syntax
public static string[] GetDirectoriesTransacted(
	KernelTransaction transaction,
	string path,
	string searchPattern,
	SearchOption searchOption
)

Parameters

transaction
Type: Alphaleonis.Win32.FilesystemKernelTransaction
The transaction.
path
Type: SystemString
The directory to search.
searchPattern
Type: SystemString
The search string to match against the names of directories in path. This parameter can contain a combination of valid literal path and wildcard (WildcardStarMatchAll and WildcardQuestion) characters, but does not support regular expressions.
searchOption
Type: System.IOSearchOption
One of the SearchOption enumeration values that specifies whether the searchOption should include only the current directory or should include all subdirectories.

Return Value

Type: String
An array of the full names (including paths) of the subdirectories that match the specified criteria, or an empty array if no directories are found.
Exceptions
Remarks

The names returned by this method are prefixed with the directory information provided in path.

The EnumerateDirectories and GetDirectories methods differ as follows: When you use EnumerateDirectories, you can start enumerating the collection of names before the whole collection is returned; when you use GetDirectories, you must wait for the whole array of names to be returned before you can access the array. Therefore, when you are working with many files and directories, EnumerateDirectories can be more efficient.
